Outpost commander
From Tardis Wiki, the free Doctor Who reference
The Time Lords believed the Gold Dalek who oversaw Operation Divide and Conquer and the Time Paradox Incident to be a subordinate "outpost commander" who deputised for the Dalek Supreme. (PROSE: Dalek Combat Training Manual)
The Dalek Survival Guide noted this unit as a Dalek Supreme yet also claimed the Dalek was never called by that rank, leading to the theory that it was actually a sub-commander or Chief. (PROSE: Dalek Survival Guide) Other Daleks of the same casing design were concretely called Supremes, however. (AUDIO: Poison of the Daleks, Eye of Darkness)
